i J. J/'asmf Patented Sept. 29, 1936 UNITED STATES PATENT GFFICE 1Claim.

This invention relates to a signal button structure primarily designedfor use in connection with the modern or conventional type of iire hoseapparatus and particularly in a signal circuit means attached to thehose, its nozzle, or otherwise.

The improved button and its circuit venables the members of a re-ightingforce to signal the engineer, who is usually distant therefrom, fromtime to time as more or less pressure is required or it is desired todiscontinue or resume the supply of water.

The more specific objects and advantages will in part be pointed outhereinafter and otherwise become apparent from a consideration of thedescription following taken in connection with ac companying drawingillustrating an operative embodiment.

In said drawing:

Figure 1 is a view in side elevation showing the invention applied tothe nozzle of nre-fighting hose;

Figure 2 is a view primarily in longitudinal section, with the partsseparated to disclose details;

Figure 3 is a view primarily in longitudinal section through theprotector;

Figure 4 is an end elevation of said protector;

Figure 5 is a central longitudinal section through the nut member;

Figure 6 is a central longitudinal section through the plug member; and

Figures 7 and 8, are primarily longitudinal sections of the contactmembers employed.

Referring specically to the drawing, wherein like reference charactersdesignate like or similar parts, the preferred and illustratedconstruction of circuit closer or button for controlling the signallingsystem embodies a thimble or nut 3, of which the reduced portion 4 isdesigned to receive the extremities of conductors 6 and I and in thebody portion of which is threaded a fiber or insulating plug 5 bored toform seats for the terminals 6, I to which the extremities of theconductors 6 and I are attached and which are respectively provided withopenings or sockets 8 and 9 to facilitate such attachment. The terminalI has a threaded opening Il! at its outer end for the reception of ascrew I by which a switch tongue II may be attached thereto to bridgethe interval between and come into contact with the terminal 6 whenactuated by the stem I2 of the push button I3 slidably mounted in abarrel I4 which screws onto plug 5 and which stem is yieldingly heldretracted by a spring I4 in a recess in said barrel and heldin place bya barrel I' screwed to barrel I4'.

As above indicated this circuit closer mechanism including the signalbutton and related parts is adapted to be carried by the hose nozzle Nor by one of the distributing or consolidating hose coupling members,and for the protection thereof to prevent accidental operation thereof,with the resulting vconfusion so far as the engineer is concerned, aprotector I5 is preferably used to embrace the same, such protectorbeing particularly shown in Figure 1 and being designed to enclose thebutton I3 and the adjacent parts of the device and being provided with acap or disk I6 normally closed by a spring I 6 having an operating knobI1. This protector may be made either of hard rubber or of metal such assteel, according to whether it is used on the hose nozzle orupon one ofthe hose coupling members where it is subject to pressure by the feet ofpassersby or vehicles attempting tocross the hose. It will be noted byreference to Figure 1 that in order to obtain access to the button toclose the circuit it is necessary to turn the cover or cap back bypressure on the knob I'I and then insert the finger in the end of thetube I5.

Various changes may be resorted to provided they fall Within the spiritand scope of the invention.

What I claim is:-

A device of the class described comprising a thimble adapted to receivethe terminals of a pair of electric conductors, said thimble having anenlarged portion, a plug of insulating material screw-threaded into theenlarged portion, a pair of spaced contacts carried by said plug, one ofsaid contacts extending beyond the plug into said enlargement and inengagement With the end wall of the enlargement in the thimble and haveing an enlarged portion provided with an angularly disposed socket, oneof said conductors being disposed terminally in said socket and theother conductor being engaged With the other contact, said enlargedportion preventing displacement of said one Contact outwardly from saidplug, said plug projecting beyond the thimble, a barrel threaded on saidplug beyond the thimble, means carried by the plug operative to bridgethe contacts, and means carried by the barrel operative to actuate thelast mentioned means.
